Liz, I understand your reluctance and concerns. Being thought of as crazy (initially) by your parents probably isn't as bad as it sounds.

Part of getting those confusing and scary experiences under control is through medical treatment. For that you should see a psychiatrist who can consider your situation more closely and correctly diagnose your condition. It will probably take your parents' buy-in to get you there.

That is the tricky part - getting them to help you without freaking out and denying there is a problem.
